In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 940MX 2GB are massively better than the Nvidia GeForce Go 7900 GTX.

The GeForce 940MX 2GB was released over three years more recently than the Go 7900, and so the GeForce 940MX 2GB is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the Go 7900 when running the latest games.

The GeForce 940MX 2GB has 1536 MB more video memory than the Go 7900, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The Go 7900 has 22.4 GB/sec greater memory bandwidth than the GeForce 940MX 2GB, which means that the memory performance of the Go 7900 is slightly better than the GeForce 940MX 2GB.

The GeForce 940MX 2GB has 384 Shader Processing Units but the Go 7900 does not have an entry, so the two GPUs cannot be reliably compared in this area.

The GeForce 940MX 2GB requires 25 Watts to run and the GeForce Go 7900 GTX requires 45 Watts. The Go 7900 requires 20 Watts more than the GeForce 940MX 2GB to run. The difference is not significant enough for the Go 7900 to have a noticeably larger impact on your yearly electricity bills than the GeForce 940MX 2GB.

GPU Mini Review

Mini ReviewOverview
GeForce 940MX 2GB is a Middle-Class Mobile Graphics Card based on the Maxwell Architecture.

Architecture
GeForce 940MX 2GB Features a GPU Codenamed GM108-N16S-GTR which is a First Gen Maxwell GPU and is identical to the GM108-N16S-GT-S used on GeForce 940M but with the addition of GDDR5 Support.
GM108-N16S-GTR has 3 Compute Units Unlocked and thus offers 384 Shader Processing Units, 24 TMUs and 8 ROPs.

GPU
The Central Unit is Clocked at 1122Hz and goes up to 1242MHz, in Turbo Mode.

Memory: Speed
The GPU is equipped with DDR3 and Accesses the Frame Buffer through a 64-bit Memory Interface. The Memory Clock Operates at 1001MHz.

Memory: Frame Buffer
The GPU can fill up a Memory Pool of up to 2GB.

Power Consumption
With a rated board TDP of 25W, it is suited for small and medium sized laptops.

Performance
Equipped with DDR3, GeForce GT 940MX is only slightly faster than GeForce GT 940M.

System Suggestions
GeForce 940MX 2GB is best suited for resolutions up to and including 1366x768. We Recommend a Middle-Class Processor and 8GB of RAM for Optimal Performance.
GeForce Go 7900 GTX is a high-end-class level GPU.
It can use up to 512MB of dedicated video memory, and it's only available with a DDR3 memory type + a 256 bits Memory Bus Width.
Due to its features and unlike the previous GeForce Go models, it should be able to play today's games, that use DirectX 9 (e.g. Sims 3, Anno 1404 and even Crysis) at the lowest settings.
